of the door movements and also to the influence of'the cooler outsideair whenever the door is opened. The disadvantages 'of each of theseconditions are, of coursefreadily apparent. The thermometers have beenthus located because of the presence of heating spaces about the sidesof the ovens and because the front walls of the ovens usually consistentirely orisubstantially entirely of the oven doors. The mounting andlocation of the oven thermometers, prior to this invention, havetherefore been confined to the front walls, which usually meant the oven'doors.

'Broadly, the objects of the present invention are to so locate an oventhermometer thatit will be permanently fixed in position and will beprotected against the shocks and jars of door movements and against theinfluenceof outside atmosphere. 7

A more specific object of this invention is the location of athermometer through a side flue or heating space of an oven withoutsubjecting it to the temperature influence of the flue or oven heatinggases passing through such space.

Another object of the invention is the location ofan oventhermometerthrough a side flue or heating space of an oven and at the same side ofthe stove as a water heating tank or reservoir positioned adjacent theflue space without subjecting the thermometer to the temperatureinfluence of the reservoir, "and by so mounting the thermometer toprotect it against accidental mechanical injury.

Numerous other objects and advantages of the invention will be apparentas'it is better understood from the following description, which, takenin connection with the accompanying drawings, discloses a preferredembodiment thereof.

Referring to the drawings Figure-1 is a partial elevation of a stoveembodying the invention;

Fig. 2 is an enlarged partial vertical section taken transversely of thestove and through the temperature indicating device, the latter beingshown in full lines, and

Fig. 3 is an enlarged section taken substantially on the line 33 of Fig.1.

For the purpose of illustrating the invention, the drawings show a coalstove 11 supported on legs 12. A suitable combustion unit or source ofheat 13 is providedto heat the stove 11 and a usual oven 14 of thestove.

VVhile the drawings show a coal range, it

will be understood that the invention may be embodied in various typesof stoves and ovens, the sources of heat of which may be provided from ausual or preferred construe tion such, or example, as that illustratedat 13 in Fig. 1.

The products of combustion from the source of heat 13 pass up and acrossthe top of the oven 14 and down into a flue or oven heating space 15which is provided-between the outer right side wall 16 of the stove andan adjacent wall 17 of the oven 14. I This flue space 15 is closed atits front by a front wall 18 of the stove, this wall 18 providing ausual oven opening closed by a suitable oven door 19.- It will beobserved that the front wall of the oven itself consists entirely, orsubstantially entirely, of the oven door 19. The Wall 18 has a marginalflange 21' which extends from the outer right corner of the stove towardthe back, as shown in Fig. 3, co-operating with an inwardly disposed,marginal olfset portion 22 of the right stove wall 16 and suitablysecured thereto to provide a corner closure for thefiue space 15.

A pocket, generally indicated by the ref erence character 23, is set offin the flue space 15 at the front of the stove by partition walls ormembers 24, 25 and 26 formed integrally with the wall 17 of the oven 14.The walls 24 and 25 extend outwardly from the oven wall 17 and arearranged horizontally in spaced relation so that the wall is above thewall 24, as shown in Fig. 2. These walls 24 and 25 are connected alongtheir rear edges by the vertical wall 26 which extends outwardly fromthe oven wall 17. The partition walls 24, 25 and 26 cooperate with theside wall 16 and the front wall 18 to form the pocket 23 and to seal itfrom the flue space 15, leaving the pocket open at its side adjacent theoven 14 and in communication with the oven.

A tube or thermometer shank 27 is arranged through an opening 28 in theside stove wall 16 and extends into the pocket 23. A collar 29 having aflange 31 is provided to embrace a portion of the shank 27 for mountingthe shank in the pocket 23 by suitable bolt and nut assemblies 32, whichsecure the flange 31 of the collar 29 to the inner face o f the stovewall. 16. The collar 29 and the flange 31 hold the shank 27 in place andthe flange seals the opening 28. The thermometer shank 27, disposed inthe pocket 23, is provided at its inner end with a plurality ofperforations or openings 33 to permit the atmosphere of the oven 14 toreach a suitable heat sensitive member (not shown) of the thermometerwhich actuates an indicating member 34 of the thermometer positioned atthe outer end of the shank 27, outside of the oven 14, and a waterheating tank or reservoir 35 is or may be mounted at the same side ofthe stove, as shown in Fig. 3. The indicating member 34 is provided witha suitable scale 34' for indicating the temperature of the oven.

The reservoir 35 is provided with a wall 36 which is positioned adjacentthe wall 16 of the stove and a front wall 39 extending out wardlylongitudinally of the stove behind the indicating member providing aspace 38 between the wall 39 at the reservoir 35 and the indicatingmember 34 of the thermometer, the space 38 supplementally insulating theindicating mechanism from the temperature influences of the reservoir Acheck or front finish plate 42 is suitably secured near the front of thestove and extends outwardly therefrom in front of the reservoir 35, asshown in Fig. 3, to form a space 37 between the front wall 39 of thereservoir to the rear of the indicating member 35 and the cheek plate 42in front of the indicating member.

The cheek plate 42 is made to provide a sight aperture or recess 43 nearits edge adjacent the side of the stove, the aperture or recessregistering with the scale 34 of the thermometer to readily permitobservation of the temperature of the oven. indicated thereby. Therecess 43 is cast in the plate 42 to provide a finishing head 44 aroundits edges, as shown in Figs. 2 and 3.

By thus mounting the thermometer, all of the advantages of the locationthrough the door are preserved and the disadvantages are eliminated. Astationary mounting is thus provided through a side flue or oven heatingspace and at the same side of the stove as a water heating tank orreservoir, the thermometer extending into the side flue space of theoven and being readily observable. Such a stationary mounting eliminatesthe misadjustments of the thermometer which are caused by thejars andshocks of door movement, and eliminates the inaccuracies of thethermometer which are caused by exposing it to the influences of thecooler temperatures outside of the oven when the door is open. Thethermometer, being located in the space 37 between the plate 42 and theend 39 of the reservoir, is protected against accidental mechanicalinjury and while the thermometer extends into the flue space 15, it isprotected from the influences of the reservoir and the flue space.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that various changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.
